WARNING!
Risk of injury in case of missing or faulty protective equipment.
After performing maintenance work, attach all safety
equipment (covers, safety precautions, ground cables etc.).
Replace the faulty parts and those which have become
unusable.
Before mounting the delivered components disconnect the printing
system from the power supply and close the shutoff valve at the
applicator.
Couple the applicator to devices using extra low voltage only.
Before making or undoing connections, switch off all devices involved
(computer, printer, accessories etc.).
In operation, moving parts are easily accessible. This applies
especially for the zone, where the pad is moved between the starting
and the labelling position. During operation do not reach into that zone
and keep long hair, loose clothes, and jewellery distant.
Before any manipulations in those areas, close the shutoff valve.
Operate the applicator in a dry environment only and do not get it wet
(sprayed water, mist etc.).
Do not operate the applicator in explosive atmosphere and not in
proximity of high voltage power lines.
Operate the applicator only in an environment protected against
abrasive dust, swarf and other similar impurity.
NOTICE!
With the open printing unit (due to construction) the requirements
of EN 62368-1 regarding fire protection casing are not fulfilled.
These must be ensured by the installation into the end device.
Maintenance and servicing work can only be carried out by trained
personnel.
Operating personnel must be trained by the operator on the basis of
the operating manual.
Carry out only the actions described in these operating instructions.
Any work beyond this may only be performed by epecially trained
personnel or service techniciens.
Unauthorized interference with electronic modules or their software
can cause malfunctions.
Other unauthorized work or modifications to the applicator can
endanger operational safety.
There are warning stickers on the applicator that draw your attention
to dangers. Therefore the warning stickers are not to be removed as
then you and others cannot be aware of dangers and may be injured.
When incorporating the unit into the overall system, make sure that
safety precautions are taken so that no-one is able to reach into the
working area.

CAUTION!
Damages of the plunger rod, cylinder tube or the seals caused
by lateral forces that affect the plunger rod of the cylinder. This
can lead to a reduction of lifetime and to leakages up to
destruction of the cylinder.
Lateral forces must be avoided necessarily.

CAUTION!
There is a risk of injury due to the movement
of the pad downwards and back up again.
Do not reach into the working area of
the pad.
Keep hair, loose clothing and items of
jewellery out of this area.
When incorporating the unit into the
overall system, safety precautions
must be taken so that no-one is able
to reach into the working area.

3.2 Sensor
The impact of the pad on the product and the reaching of the blow-off
position are detected by means of an inductive proximity switch and a
spring-mounted cam disc. The distance between the cam disc and the
inductive proximity switch is used.
The start position is the upper end position of cylinder and the position
of the pad which takeover the label from printer. This position will
detected via a Reed-sensor in interaction with a magnet mounted
inside cylinder.
The correct transfer of a label will be checked by the vacuum sensor.
It also checks that there is no longer a label on the pad in case the
return movement. This sensor is integrated to the APX connection
PCB.
The pressure sensor controls the pressure air. This sensor is
integrated to the APX connection PCB.

3.3 Pneumatic
A cylinder with stroke of 100 500 mm is used for the transport of
labels between the peel-off edge of the printer and the labelling
position. The movement of cylinder is controlled by a control valve on
the valve block.
The speed of movement can be changed by two throttle valves
mounted at the cylinder.
The label will be transported by a pad. The pad must be appropriate to
the size of label.
During the label transport a vacuum is applied on the pad.
In operating mode 'blow on' in the lower final position the label is
applied by a high pressure.
The vacuum at the pad is produced by a vacuum generator. The
vacuum generator is controlled by control valve on the valve block.
The low pressure can be adjusted by a throttle valve.
Air is blown from below (supporting air) through a blow tube onto the
label in order to support the transfer of the label from the printer to the
pad. The blow tube is adjustable concerning the blowing direction.
The supporting air is connected by the magnet valve (support air). The
power of the supporting air can be adjusted by a throttle valve at the
valve block.
The pneumatic maintenance unit is offered as an option for the
applicator. The important components of the pneumatic maintenance
unit are a pressure reducer with manometer, a water separator with
micro filter and a main connector for compressed air.
The distribution of the compressed air to the various pneumatic units
is made in the valve block.
On the valve block is mounted the control valve for support air and
vacuum with their throttle valves and the control valves for the lift
cylinder and blow air.

with integrated switch (E-K, C-J, B-I).
If the printer is switched on the valve will controlled by electronics and
the tamp will hold in the upper end position (home position). If the
valve switched the tamp will move in the lower end position (labelling
position). In normal labelling operation the movement back in the
upper end position will start by a signal from labelling sensor.
NOTICE!
The switching by hand of this valve has only a result in case of
a switched off printer.
Switching the valve by hand over switch (E) the tamp will move down
up to the lowest possible position because no control is made by the
sensor.
Switching the valve by hand over switch (K) the tamp will move up.

In the operation mode 'Blow on' the label will blow up to the product.
In the operating modes 'Stamp on' and 'Roll on' the blow air is
switched on for a short time after each application to avoid
contaminations within the vacuum channels.
For all described functions both valves will be controlled parallel.
By pressing the keys (C) or (J) the blow air is only switched on by one
of both internal valves.
The two internal valves serve the vacuum nozzle for connecting an in
this way for creating the negative pressure at the tamp and
independent of this for connecting the support air at the blow tube for
the label transfer.
By pressing switch (B) the vacuum is switched on and by pressing
switch (I) the supporting air is switched on.
